Boxer Brown

A new poll from the Public Policy Institute of California finds the candidates for governor are virtually tied, while the incumbent Democrat has a slight lead in the U.S. Senate contest, with just over a month remaining before the Nov. 2 election.

The survey, released Wednesday, finds Republican Meg Whitman has 38 percent support among likely voters in the California governor's race, compared with 37 percent for her rival, Democratic Attorney General Jerry Brown. About 18 percent of voters are undecided, while more than half the respondents said they were not satisfied with either choice.

In the Senate race, Democratic Sen. Barbara Boxer has 42 percent support among likely voters, while the Republican candidate, former Hewlett-Packard Co. chief executive Carly Fiorina, has 35 percent support. Nearly one in five voters is undecided in the race.
